Genuine OEM Land Rover Lower Spring Insulator, part number LR003915. This component is designed to provide crucial cushioning and noise damping between the suspension spring and its mounting point. Positioned at the lower end of the spring, it helps absorb vibrations and prevent metal-on-metal contact, contributing to ride comfort and reducing NVH (Noise, Vibration, and Harshness). Made from durable rubber or elastomer, it maintains its integrity under constant load and environmental exposure. Choosing a genuine OEM spring insulator ensures the correct material composition and precise dimensions for factory-level performance and longevity.
